Red Velvet held a V Live session and shared their thoughts about their upcoming comeback. The session was a “lying down broadcast” where the members talked lying down amongst fluffy pillows and dressed in comfortable pajamas. The members, contrary to their bright, energetic image, expressed their worries.

Prior to the “lying down broadcast,” the members had held a showcase where they performed their new title track “Peek-A-Boo” for the first time. Bringing up how their music is categorized into two types of concepts, a “red” concept and “velvet” concept, they commented during the showcase.
